1. md5
------
When running lbackup, at some point the command md5 is invoked:
/usr/local/libexec/lbackup/message_templates/mail_logerror_attachment.sh
(line 47)
and in the same directory
mail_standard_attachment.sh (line 45)
On ubuntu, md5 seems not to be part of the standard distribution, at
least not by that name. On ubuntu the respective command is md5sum.
2. sendmail
-----------
sendmail is not configured on my system:
sendmail: fatal: open /etc/postfix/main.cf: No such file or directory
It seems a big requirement needing to configure sendmail just for
sending mail from a shell script.
There's a dead simple to use alternative: sendemail
(http://caspian.dotconf.net/menu/Software/SendEmail/).
It's perl-based but requires no other modules, hence runs off the
cuff. It supports everything required by lbackup including attaching
files, yet in a simpler way (e.g. no need to base64-encode attachments
"manually").
Replacing sendmail with sendemail would also rid us of the missing md5
problem (1. above). If anyone's interested I could provide patches.
3. symlinks and samba
---------------------
My destination for the backup happens to be a mounted samba drive which
lacks support of symbolic links. These occur in some situations of my
source to be backed up.
Is there a standard way to deal with this situation?
(I think none of rsync's options satisfactorily handle this particular
case: I would like to reproduce the exact same state from my backup.
--links: With the target filesystem's lack of support for symbolic
links, simple copying is not available.
--copy-links: Collapsing of links is not the same as keeping them verbatim)
4. rsync options
----------------
Is there a standard way to plug in options into the rsync command
invoked by lbackup?
Maybe lbackup could do a prerequisite check whether all required tools
are present? And possibly dispatch to different commands depending on
the OS?
E.g.
if uname -a | grep -i ubuntu >/dev/null 2>&1; then
MD5=md5sum
else
MD5=md5
fi
Thanks
Bernhard
